hello, i hope you still played it until now but if you didn't, i advice you to download this https://pooi.moe/Locale-Emulator/ and to do what they tell you in this site. i tried it and it worked for me so i hope it'll work for you as well :)
Thank you so much! I was able to play the game but there's just a little problem... After booting up the game for a second time, the data doesn't save.
It saves however, if I am still playing the game. Please help?
